SLE 66CL80P
General Description
The dual interface security controller SLE 66CL80P is a member of the Infineon Technologies
SLE 66CxxxP high-end security controller family in 0.22 µm CMOS technology which is designed
for security systems that requires continuous ongoing improvements with the highest degree of
protection against fraudulent attacks.
SLE 66CL80P is targeting both contact-based and contactless smart card applications such like
Banking, Pay TV, security access, digital signature and transport.
SLE 66CL80P offers 70 Kbytes of User-ROM, 256 bytes internal RAM, 2048 bytes XRAM and
8 Kbytes EEPROM, which can be used as data and as program memory. The non-volatile memory
consists of high reliability cells to guarantee data integrity. This is especially important when the
EEPROM is used as program memory.
It features ISO/IEC 14443 Type A and B contactless interfaces as well as an ISO/IEC 7816
contact-based interface on a single chip that can be operated in parallel. It also supports
symmetric and asymmetric public-key algorithm such like DES and Elliptic Curve independently of
the operation and communication mode.

The CPU provides the high efficiency of the 8051 instruction set extended by additional powerful
instructions with enhanced performance, memory sizes and security features tailored for contact
and contactless smart card applications. Using the embedded PLL, the internal clock is adjustable
up to 15 MHz independent from the external clock frequency supplied by the terminal (contact-
based and contactless).
The Memory Management Unit allows a secure separation of the operating system and the
applications. Using the system/application mode, it allows to securely downloading applications in
the field after card personalisation. Using the MMU transparent mode allows keeping the memory
mapping for code compatibility to SLE 66CxxS family. These new features suit the requirements of
the new generation of operating systems.
